Hello,
I am using Aspose.PDF for .Net 17.4 to fill a PDF form field using the following code:
Document pdfDocument = new Document(@“legal-aid-crm11-cost-summary (1).pdf”);
TextBoxField f = pdfDocument.Form[0] as TextBoxField;
f.Value = “test update”;
This throws a null reference exception when Value is being set - do I need to do something different here?
Form attached.
legal-aid-crm11-cost-summary (1).pdf (64.8 KB)
